As I opened the field, I used to be glad to see that SIG even features a high quality Alpha-MSR scope mount within the field. That simply narrowed down my mounting choices.

I’ll say I used to be shocked with all the pieces included with the scope, and I’ll be sincere that getting in I had solely a imprecise thought of the value of this optic. The mount, typical instruments that include it, battery for the illuminated reticle, and a few high quality flip caps have been additionally included. They’re branded SIG however look to be both Tenebraex or a extremely shut knockoff. Both approach, they’re very good and lay flat in opposition to the scope when open. The MSR additionally features a throw lever or “cattail” because it’s typically known as. That is useful for fast changes of the magnification.

The Tango MSR is a second-focal-plane scope. Which means the reticle stays the identical whatever the magnification setting. The scope adjustment turrets are MOA and have .5 MOA clicks. The scope physique has a centerline painted on the outside of the tube to assist guarantee stage mounting, I imagine, and it absolutely did that. In a really brief time, I had the scope married to its mount and able to set up on a rifle.

Vary Testing

I occurred to have a
SIG MCX rifle available on the time. It appeared like an ideal match for the MSR. I used to be extra right than I may have identified. I dropped the scope onto the Pic rail of the MCX, and off to the vary we went. The MSR gave the impression to be made for the MCX as I didn’t even want to regulate the scope for a superb zero, I simply began taking pictures and all the pieces lined up like they got here from the manufacturing facility that approach.


I spent a while taking pictures the rifle at pretty shut distances inside 200 yards, however I additionally utilized the reticle for a couple of prolonged distances. The reticle contains a typical upside-down horseshoe-type reticle with a number of drop factors and wind holds. The title means that the MSR is designed particularly for Fashionable Sporting Rifles (MSR), and the BDC6 reticle is calibrated for the most well-liked MSR cartridge – 5.56 NATO.

I spent the higher a part of a day taking pictures the MSR/MCX mixture. I actually appreciated the built-in throw lever. It made fast transitioning from up near far-off very straightforward. The subtensions of the BDC6 reticle have been additionally very useful for holdovers on targets that have been a bit additional out. 

As I discussed earlier, I purposely didn’t take a look at the value of this scope earlier than reviewing it. I used to be beforehand more than happy with the optical high quality of the Tango6T. This Tango MSR is just not fairly as prime quality, however it’s nonetheless very clear and clear. I used to be shocked to see the value level after enjoying with it, I’d have anticipated it to come back within the $600-$800 vary. However for the MSRP of $422.99, I believe this scope is a good worth.

I additionally bolted down the mounted scope to a bench and measured the turret values in opposition to the reticle values, which all checked out. The reticle values are useful to bear in mind, or you possibly can check with the proprietor’s handbook the place they’re listed. It might not line up completely with the drop of your specific ammunition and ambiance. Because of this I usually don’t look after calibrated reticles. That stated, if what worth they characterize, you should use them for all types of pictures and holdovers.

I additionally like to check the precise worth of the turret motion. You’d be shocked how typically they are often off even by a bit bit. In case your turret is meant to be .25-MOA clicks, however it’s really .275 MOA clicks, you’ll find that issues are notably off when vital changes are made.
